How to convert string xml to Map<String,String>
dictionary, java, xml
Solution
I just wanna this:
public static Map<String, String> convertNodesFromXml(String xml) throws Exception {
InputStream is = new ByteArrayInputStream(xml.getBytes());
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(is);
return createMap(document.getDocumentElement());
}
public static Map<String, String> createMap(Node node) {
Map<String, String> map = new HashMap<String, String>();
NodeList nodeList = node.getChildNodes();
for (int i = 0; i < nodeList.getLength(); i++) {
Node currentNode = nodeList.item(i);
if (currentNode.hasAttributes()) {
for (int j = 0; j < currentNode.getAttributes().getLength(); j++) {
Node item = currentNode.getAttributes().item(i);
map.put(item.getNodeName(), item.getTextContent());
}
}
if (node.getFirstChild() != null && node.getFirstChild().getNodeType() == Node.ELEMENT_NODE) {
map.putAll(createMap(currentNode));
} else if (node.getFirstChild().getNodeType() == Node.TEXT_NODE) {
map.put(node.getLocalName(), node.getTextContent());
}
}
return map;
}
Problem
How I can convert all value of element and attributes of xml to Map of string ? Is there some library which can do this ? I found library xStream but I dont know how to configure it.
